The Herberts of Coldbrook were descended from Sir Richard Herbert, the younger brother of the 1st earl of Pembroke. Sir Richard’s support for the Yorkists during the Wars of the Roses allowed him to build an impressive residence at Coldbrook out of the profits of confiscated Lancastrian lands, but occasioned his execution after the defeat at Banbury.
Herbert was not a particularly affluent member of Monmouthshire society, being rated at only £3 in the 1628 subsidy - less than many of his neighbours.
Herbert was a conscientious Ship Money sheriff in Monmouthshire in 1637-8, collecting all the required monies from the county apart from the assessment on the town of Newport.
In his will of 8 Mar. 1651, Herbert made provision for his younger children Thomas, Charles, William and Rachel, and constituted his heir, Henry, as his executor.
